"A good pair of running shoes can last 400-500 miles” is a running adage of unknown origin. “Most good running shoes, however, should last for at least 500 miles (800 km) without the need for replacement” was cited in The Practical Runner (1978) by Robert Geline. “I’m beginning to wonder if most of the shoes out there are good for more than, say, 400 miles” was cited in the magazine Runner’s World in 1984.

The life span is generally between 300 and 500 miles. Therefore, shoes should be replaced about every 400 miles or every 6 months. Air soles, the new composites, and gel soles may last longer.

People who run 25 miles or more a week should change running shoes every 2 to 3 months; those who run less than 25 miles a week should change shoes every 4 to 6 months. Running shoes normally retain decent shock absorption for 300 miles of use.

How long should running shoes last?

>A good pair of running shoes should last about 500 miles. At that point
>they might LOOK okay, but the support elements start breaking down to the
>point where they should be replaced.

I wholeheartedly disagree with this. Other than here and on the net, nobody anywhere will tell you that shoes only last 400 to 500 miles, and my personal opinion is only Nikes need to be replaced this soon. I just tried a pair to be an informed consumer, and after a week of running they show noticeable wear, moreso in a week than my GT2060’s show from a whole summer of mileage. Another brand that may wear prematurely is Brooks.

Signs you need new running shoes
By John Byrne
Running shoes don’t last forever, but you can’t necessarily follow the old adage that each pair will last 400 miles either. Running in old shoes can result in a variety of ailments as the shoe’s cushioning and structure breaks down, or trauma-related injuries (such as a bone bruise under the metatarsal heads) as the outsole wears thin.
